I need suggestions on what waterproof camera to buy for our office. We have had 2 staff members already take cameras for a swim. We need not weather resistant cameras, but truely waterproof to at least 5 feet (this will insure that the camera will stay intact if dropped in a stream (I think 5 feet is good, since most of us will not be able to locate a camera in deeper water). This is you tax dollars at work (federal government) so we need to keep the price under $400. Thanks !
